Well, I bought my elongated ADA Ultramax last Friday. I havn't installed it yet, still remodeling. Tile guy coming Aug.21, so shortly after that I'll see what all the fuss is about.
I did unbox it and install the seat/lid (softclose). I have my reservations about the seat, but will wait until after install for final judgement.
This toilet is very cool looking, I must say. But it sure looks small compared to the 5 gal model it's replacing.
